The gradual pop in of the trees felt solid. They weren't too sudden that I felt it was unfair, but also sudden enough that it was a good test of my reaction time. However, the placement of the trees below the player as they come down towards the screen make the perspective feel a bit awkward. I would also say the shooting could use some tweaking in terms of controlling the shot. In the original, it allowed you to shoot at more of an angle for left and right, and you could also change the direction of the shot after it came out. Those two things really helped with aiming for your targets.
